The long-awaited update of ISO 27001 arrived in October 2022, having gone 9 years since its previous 2013 iteration. Needless to say, it was much overdue.
The new 2022 version of the Standard includes 11 new controls and sees around 56 other controls combined into 24 newly titled controls.
In order to cover every aspect of the new Standard, we’ll be running a mini-series through January and February on the updated ISO 27001:2022 in addition to how you can transition to the new version.
Starting off the series strong, Mel is joined once again by Steve Mason, our very own Information Security guru, to broadly discuss the changes to ISO 27001:2022.
- Who is ISO 27001:2022 applicable to?
- An overview of the changes to ISO 27001:2022
- What is Steve’s favorite change to ISO 27001:2022?
- What are the challenges involved with updating to the 2022 version?
- ISO 27031 (Guidelines for information and communication technology readiness for business continuity)
- ISO 27005 (Risk assessment)
- ISO 22301 (Business Continuity)
In this episode, we talk about:
[01:50] Steve Gives an overview of what’s new in ISO 27001:2022 – The updated version of ISO 27001 was released on the 26th Oct 2022. The new version included 24 changes and clarifications within the main clauses.
[02:50] The controls for the new standard are now categorised into 4 groups: Organisation, People, Physical and Technology
[06:17] The 24 changes and clarifications to Clauses include older existing clauses which have been tidied up to be more transparent. We recommend reviewing to ensure that you are complying in a way that aligns with the Standard.
[06:35] There are 11 new Controls. 56 controls from the 2013 version have been reduced to 24 with 58 remaining unchanged. So, in short, Annex A has been simplified with less duplication of controls.
[07:44] Steve highlights section A.9 for Access Control as one of the much-improved controls – due to the lack of repetition and simplified requirements for compliance.
[08:35] Steve’s favourite update to the Standard: The whole Standard now collectively encourages incorporation into your business. Your ISMS should not feel like a bolt on, it should be a part of your businesses DNA.
[10:36] Steve’s favourite update to the Standard #2: It’s not a static Standard, it encourages development and continual improvement.
[13:45] For those completely new to ISO 27001 – check out our 3-part Steps to Success series which explains the Implementation process from start to finish.
[14:38] Listen to some of our client interviews to hear the challenges others faced when Implementing ISO 27001 in addition to the benefits gained as a result of adopting the Standard:
[14:50] Why would the business continuity elements of ISO 27001:2022 pose a challenge? There used to be a clause in the 2005 version of the standard which documented the need for a business impact analysis – this was removed in the 2013 version. The new ‘ICT readiness for business continuity’ control will require at the very least, a risk assessment.
[16:48] Steve recommends checking out the Plan, Do, Act, Check diagram in ISO 27031 (Guidelines for information and communication technology readiness for business continuity). It also includes some great guidance on business impact analysis.
[18:40] The ICT readiness control is not designed to be an all encompassing business continuity strategy – it’s designed to work in tandem with as existing one (you may already be certified to ISO 22301 Business Continuity Management).
[19:50] It’s highly recommended that if you don’t have a Business Continuity Plan or strategy – at least have a framework in place. Disasters by their nature are unpredictable, as is the resulting damage to an extent. You will not know the full extent until you’ve lived it – so don’t write an exhaustive 80+ page manual that no-one will read, document the what, who and how of getting yourself back up and running again.
[21:11] There has also been an update to ISO 27005 (Risk assessment in relation to info sec). It includes a new set of threat categories: physical threats, natural threats, infrastructure failures, technical failures, human actions, compromised services or functions and organisational threats. These may help you when putting a business continuity framework in place.
[22:05] Above all else – ISO 27001:2022 has modernised and aligned itself more with the likes of cyber essentials and NIST.
